.To if/ZZ whom, it may cor/toeren f Beit known that we, JONATHAN HALEY an HARRY H.-BRIDGWATER, residing at Akron, county of Summit, and State of Ohio, have invented certainY new and useful Improvel' ments in Apparatus for Forming IIollow Glass Articles; and we do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable othio ers skilled in the art to which it pertains to make and use theisame.

Our invention relates to improvements in apparatus' for forming hollow glass articles;- such, for instance, asbottles and jars; and

the invention relates more especially to the formation of hollow glass articles by first pressinggor molding a quantity of glass into a hollow form and then expanding the blank by blowing into the latter.

zo Heretofore one great obstacle encountered in an effort to manufacture a perfect jar or bottle was the imperfections appearing upon the neck of the bottle or jar and resulting from a lateral sliding or removal of the jar or bottle from one to another of the molds required or employed in the formation of the said article. The imperfections referred to consisted in crizzles formed, mainly, on the neck of the article,but formed also upon other 3o portions of the article.

The primary object of our present invention is to avoid the said crizzles 'or imperfections in the hollow glass article being formed by requiring the blankvto be moved vertically only, and hence avoiding any lateral movenient of the blank.

Other objects of thisinvention are to sirn- 1 plify the construction of apparatus of the character indicated, to render the same more 4o convenient and reliable in its operation, and to reduce the cost of hollowglassware adapted to be formed by the said apparatus.

With these objects in View and to the end of realizing other advantageshereinafter appearing the invention consists in certain features of construction and combinations of Y parts hereinafter described, and pointed out in the claims.

In the accompanying drawings, Figures I 5o and II are elevations, at right angles to each other, of apparatus embodying our invention,

and portions are broken away and in section in the said figures to more clearly show the' construction and toV reduce their size. In

.these figures the press-mpld employed in the `formation of the lower portionof the blank is shown in position below the mold instru-` mental in the formation of the neck of the article and below the plunger employed in the formation of rthe blank within the said 6o molds. Fig.{III is an elevation partly in sec'- tion and corresponding with Fig. I, except that iri Fig. III the neckeforming mold is low* ered upon the press-mold andthe plunger has formed the blank within the said molds. Fig. IV is an elevation partlyin section and corresponding with Fig. III, except that in Fig. IV

\ the plunger and the neck-forming mold are elevated the distance required to free the.. blank attached to the neck-mold from thepress-mold. 7c Fig. V is an elevation partly in section and `corresponding with Fig.,IV, except that in Fig. V the slide that carries the lpress-mold and theblow-mold is shown in the position required to bring the blow-mold and the blowplate into an operative position. Fig'. VI is an elevation partlyin section and correspond ing with Fig. VV, except that in Fig. VI the neck-mold and the blow-plate arelowered into an operative position relative to the blow- 8o mold. Fig. VII is a side elevation, mostly in section, showing the plunger, plunger-slide,

the slideways for the said slide, the neckmold, the means ofsupporting the neckmold from the plunger-slide, the blow-plate, and other parts, and the position of the parts in this figure corresponds tothe position of the corresponding parts shown in Fig. VI. Fig. VIII is a transverse section on line VIII VIII, Fig. VII, looking downwardly. Fig. IX is 9o an elevation, mostly in section, on line IX IX, Fig. VIII,-looking in the direction of `the arrow'. Fig. X is an elevation, mostly Vtransverse section,.on line XX, Fig. VIII, except thatthe blank 'm and the plunger k are not 95 shown in Fig. X. Fig. XI is a top plan of the blow-mold and its support. A Fig. XII is an elevation, mostly in section, on line XII XII, Fig. XI. Fig. XIII is a vertical section on either one of lines XIII XIII, Fig. XI, lookroo ing in the direction of the arrow.

Referring to the drawings, a designates a horizontally arranged table that forms the top of a carriage b,that is provided with wheels c to render it conveniently portable and readily movable from one place to another. A horizontally-arranged slide or mold-carrier d is mounted upon the table a and movable.

longitudinally of the carriage. The slide CZ engages, therefore, the slideway c, formed upon and longitudinally of the table a, in any approved manner. The press-mold f and the blow-mold g are supported from the slide d in any approved manner. The molds f and g are arranged a suitable distance apart and in line longitudinally of the said slide. The mold f engages,preferably, a recess 15, formed in the slide, and is provided in the usual manner with a handle 16 and with a centrally-located chamber 17, that is open at the top of the mold and is adapt-ed to receive the quantity of glass employed for pressing or molding thev blank within the said mold, as will hereinafter more fully appear. The blowmold g is in the apparatus illustrated arranged between the press-mold f and a column or post 18, that is instrumental in actuating the blow-plate h from an inoperative to an operl ative position, or vice versa. The plate h rests upon the neck-mold Z. The blow-mold has its 'chamber open at the top in the usual manner to accommodate the passage of the blank into the said mold and the subsequent operation upon the blank.

The post or column 18 is rigid with the slide d, and the blow-plate h has a passage-way 20 (see Fig. X) extending therethrough and employed in establishing open relation between the interior of the blank introduced into the blow-mold and the flexible blow-tube 21, that is attached to the blow-plate in any approved manner at the receiving end of the passageway 20.

A vertically-movable vertically-arranged plunger 7c, that is supported and operated as will hereinafter appear, is employed in forming the blank within the moldsfand l. The plunger 7c is therefore arranged in the vertical pla-ne that contains the mold l and has such arrangement relative to the chamber of the neck-mold that the said chamber and the aforesaid plunger shall be in registry at all times and the plunger and the neck-mold shall be in line with the press-moldf or with the blow-mold, according as the latter or the former is upon actuating the slide d in the required direction moved in under and in line with the neck-mold and the plunger.

As already indicated, the apparatus illustrated is more especially designed for forming hollow glass articles-such, for instance, as a jar or bottlehaving a neck provided with an external rib, thread, ange, or other configuration that will render the article or the blank capable of being suspended from the-neck-lnold employed in the formation of the said neck. The neck-mold Z is provided wtha centrally-located chamber 80, that is open at top and bottom ,which chamber has its surrounding wall conforming to the external configuration of the neck that is to be formed upon the blank. The neck-mold l has such an arrangement relative to the path of the press-moldf and the blow-mold g that, as already indicated, the blow-mold or the pressmold is brought into registry with and below the neck-mold upon moving the slide d in the direction and to themextent required without necessitating a lateral movement of the neck-mold. The plunger k and the chamber of the neck-mold are in registry, and the chamber of the neck-mold has such 'dimensions transverselyrelative to the thickness of the plunger as will accommodate the passage and operation of 'the plunger centrally through the neck-mold and at the same time leave enough space surrounding the plunger to form a suitable thickness of glass between the plunger and the surrounding wall of the neek-molds chamber. The neck-mold and the plunger are movable together vertically to a limited extent, as will hereinafter fully appear, and of course preparatory to the movement of the press-mold f upon supplying the latter with the requisite quantity of molten glass f (see Fig. 1) in under the plunger and the neck-mold the latter and the plunger are elevated, it' not already, the distance required to accommodate the movement of the press-mold below the neck-mold. When the glass-laden press-mold has been brought below and into registry with the neck-mold, the neck-mold is lowered into an operative position upon the press-mold and the plunger is lowered in to the press-m old through the neckmold and forms the blank within the said molds, as shown in Fig. lll. During the operation of the plunger 7e some of the molten-glass is displaced upwardly into the neck-mold and into any diametrical or lateral enlargement of the chamber 30 of the said mold, so that when the plunger and the neck-mold are subsequently withdrawn from the press-mold the blank will be suspended from the neck-mold. For instance, the neck-mold illustrated has the upper end of its chamber() enlarged diametrically, so as to form an upwardly-facing annular shoulder 31, over which some of the molten glass is displaced during the blankforming operation, and consequently the blanks upper end, that overlaps the said shoulder, prevents the blank, and consequently the finished article, from dropping from the neck-mold until released by the latter upon separating the sections composing the said mold, as will hereinafter appear.

m designates the blank, and 40 the lip, iange, or diametrical enlargement of the upper end of the blank and overlapping the shoulder 31 of the neck-mold. (See Figs. VII and IX.)

When the neck-mold and the plunger have been withdrawn from the press mold far enough to remove the blank from the pressmold,as shown in Fig. IV, the slide d is shifted endwise to remove the press-mold from ill loo l IIO under the neck-mold and to bring' the blowmold below the blank and into registry with the neck-mold and the plunger, as shown in Fig. V, whereupon the neck-mold is lowered as required to introduce the blank into the blow-mold, as shown in Fig. VI, and to bring the neck-mold iuto'operati ve position relative to the blow-mold.- The actuation of the slide d as required to bring the blow-mold into registry with the neck-mold results in the actuation of the blow-plate 7L upon the neckmold, as will hereinafter more fully appear, into an operative position relative to the neck-mold and the blank suspended from the neck-mold, so that air under pressure now introduced into the blow-plate will be conducted into the blank and expand the latter within and in conformity to the blow-mold. It will have been observed that by our improved construction the blank is moved verticallyin removing it from the pressmold and in subsequently lowering it into the blowmold without being` moved laterally, and consequently any crizzles or other imperfections that would be formed in the blank from a lateral movement of the latter are avoided.

The neck-mold is preferably constructed to render it instrumental in forming the upper extremity of the body of the bottle or jar being made, and hence the chamber of the central or neck-forming portion of the said mold is enlarged diametrieally at its lower end, as

at 32, (see Figs. IX and X,) so that the body of the article being blown within the mold will be expanded into the said enlargement of the neck-molds chamber and cause the neck-mold to form or shape the upper `end of said body, as shown in dotted lines, Fig. VI.

The blow-mold, as well as the neck-mold, is made in sections that are readily separable to accommodate the removal of the finished article from the said molds.

A mold-ringj is employed in the formation of the upper edge or end of the bottle, jar, or article being made. The upper diametrical enlargement ot' the chamber 30 of the neckmold is not only large enough to accommodate the displacement of glass over the shoulder-forming bottom'l of the said enlargement, but to receive the mold-ringj, that is provided with an internal annular recess 14, (see Figs. III and VIL) whose surrounding wall has the form required to mold or shape the lip or iiange 40 desired to be formed upon the upper end of the blank, as shown more clearly in Fig. Ill, wherein the mold-ring is in position upon the shoulder 3l. The ring j is preferably detachably secured, by means of screws 13, (see Fig. VIL) to the lower end of a cushion that is suspended from the stem 46 and comprises, preferably, two horizontal plates 25 and 26, arranged a suitable distance apart vertically, and springs 27, interposed between the said plates. The springs 27 are spiral springs coiled upon bolts 28, that are screwed into Lthe lower plate 25, extend easily through the upper plate 26, and have their heads arranged at the upper side of the upper plate. The upper plate 26 is rigidly secured to the stem 46 in any approved manner, and the lower plate loosely embraces the plun ger 7l; and has its centrally-located hole 24 (see Fig. VII) large enough to`freely accommodate the location and operation of the plunger. The arrangement of the parts is such that during the pressing operation of the plunger the mold-ring enters the neck-mold and somewhat yieldingly engages the upper end of the blank.

Two columns or standards n and n are rigidly secured to the table a opposite each other and at opposite sides, respectively, of the path of the plunger and the neck-mold. A yoke 43 ties together and braces apart the upper ends of the standards 'n and n and is secured to the said standards in any approved manner. The plunger 7o is arranged centrally between the standards n and n land is rigid with and depends from the under side of a slide 45, that is properly denominated the pl linger-slide, and is arranged horizontally and between the standards 'n and n, that are partially embraced by the ends of the slid e, and consequently form slideways for the slide. The plunger-slide at the top and centrally is provided with an upwardly-extending vertically-arranged stem 46, that extends through and has bearing within a box 44, formed centrally of the yoke 43 and extending a suitable distance below the said yoke. Two arms o and o are pivoted horizontally at and 'to opposite sides, respectively, of the said box-forming depending member 44 oi" the yoke 43 and extend laterally of and upwardly` from the yoke a suitable distance above the yoke, and a lever p is fulcrumed horizontally to and between the upper ends of the said arms o. The said lever extends laterally of its fulcrum to and over the yoke in the one direction and extends laterally of its fulcrum Ain the opposite direction and has its last.-`

mentioned portion provided with a poise or counterbalance q. Thelever pis operatively connected with the plunger-slides stem 46 in any approved manner and is provided with a handle 50 at the upper end of the said stem. The leverp is of course instrumental in operating the plunger.

The neck-mold is normally supported from the plunger-slide and in the apparatus illustrated is supported from two slides tand t, (see Figs. VII and VIIL) that partially embrace the different slideway-forming columns or standards n and n, respectively, and are provided with nvertically arranged upright studs or rods 55, that extend easily through vertical holes or perforations 56, formed in the plunger-slide 45, and having' their upper` ends provided with heads or members 57,0verlapping the upper side of the plunger-slide.

p In the normal position of the parts the heads or members 57 ot' the rods or studs 55 overlap and rest upon the upper side of the plungerslide, and consequently the neck-mold is sus- IIO pended from the plunger-slide, as shown in Figs. II and VII. Upon lowering the plunger-slide by properly manipulating the lever p the plunger and the neck-mold are lowered simultaneously until the neck mold rests upon the pressrnold f or the blow-mold g, according as the press-mold or blow-mold is below andin line with the neck-mold. The neckmold lowers by gravity. The hereinbeforedescribed peculiar connection of the neckmold with the plunger-slide permits the said slide, and consequently the plunger, to move downwardly independently of the neck-moldwhen the latter is in position upon the pressmold or upon the blow-mold.

The blow-plate is swiveled upon or vertically pivoted at one end, as at 19, to the neckmold support at one side of the neck-molds chamber and near one of the columns or standards n, as shown more clearly in Figs. VIII, IX, and X. The receiving end of the passageway 20, extending through the blow-mold, as

shown in Fig. X, is in open relation with theA tube 2l. The discharging end of the said passage-way is in openrelation with the interior of the blank when the blow-plate is in an operative position relative to the blankcarryingneck-mold. I-Iencethe arrangement of the parts is such that the blow-plate is rendered operative or inoperative, according as it is swung into the' one or the other of its extremepositions. Ahorizontally-arranged box or sleeve 22 is swiveled, as at s, as shown in Fig. X, upon the blow-plate near the central portion of the plate. The rod or bar 23 has bearing in and extends through the box 22 and is journaled at one end upon and movable up and down the post or column 18. Two shoulders 24 and 24 are formed upon the bar or rod 23 a suitable distance apart aud at opposite ends, respectively, of the sleeve or box 22, and the arrangement of the parts is such that the one or the other shoulder 24 shall abutagainst the box, according as the blow-` plate is swung into the one or the other of its two positions. Hence one'of said shoulders constitutes a stop to limit the movement of the blow-plate in the one direction, and the other shoulder forms a'stop that limits the movement of the said plate in the opposite direction. The hereinbefore-described peculiar connection of the blow-plate with the post or column 18 accommodates the descent of the blow-plate with the neck-mold when the latter is lowered u pon the blow-mold preparatory to the blowing operation.

Two cams rr are arranged at opposite sides, respectively, of the plunger-slides stem and are pivoted horizontally, as at 5l, to and transversely of opposite sides, respectively, of the lower end of the box 44, below the aforesaid arms o. A lever or handle 52 is attached to both of the said cams in any approved manner and is capable of simultaneously operating both cams. The different cams r are arranged to operate upon different shoulders, respectively, formed upon opposite sides, respectively, of the aforesaid stem, a' suitable distance below the box 44 and between the said box and the plunger-slide. The shoulders are formed, preferably, by different rollers s and s, respectively, arranged horizontally at and supported from opposite sides, respectively, of a collar 47, that is fixed upon the aforesaid stem, preferably by means of the set-screw 48. The arrangement of the cams and the antifrictionrollers is such that when the plunger is at the elevation required to render it capable of descending upon the blow-plate when the latter is in an operative position upon the neck-mold, the tilting of the cams downwardly upon the shoulder-forming rollers s lowers and holds the plunger downwardly upon the blow-plate, as shown in dotted lines, Fig. VI.

A valve-casing connects together and is interposed between the liexible tube 2l and an air-pressure-supply pipe 6l. A plug-valve 62 is arranged to operate within the said valve-casing, and the port 63, (see Fig. 1,) that extends through the plug, is arranged as required to render it capable of establishing or interrupting open relation between the tube 2l and the pipe 6l, according as the'plug is turned into the one or the other of its extreme positions. The plug is provided at one end and outside of the valve-casing with a lever 64 for turning the plug, and a link G5 operatively connects the said lever with the cams r, and the arrangement of the said parts is such that the plug shall be closed in the normal position of the parts, as shown in Fig. I, and shall be opened simultaneously with and by the operation of the cams r, so that when Vthe blow-plate is in an operative position and properly held down upon the neck-mold the air-pressure-supply pipe shall be in open relation with the passage-way in the blow-plate. Y

The operation of the apparatus hereinbefore described is as follows: Preparatory to the commencement of the operation ofthe machine the plunger and the neck-mold are elevated to permit the movement of the pressmoldfunderneath theneck-mold. Aquantity of molten glass required to form a blank is introduced into the press-mold, whereupon the mold-bearing slide CZ is actuated in the direction required to bring the said mold in under and into registry with the neck-mold.

The stem 46 and the connected plunger and the neck-mold are then lowered by tilting the handle-bearing end of the lever p downwardly. during the lowering of the plunger, so that when the neck-mold has been lowered into an operative position upon the press-mold it is capable of being further lowered independently of the neck-mold, and the plunger, in its descent, after the neck-mold has been lowered upon the press-mold, passes into the press-mold through the neck-mold, and presses or displaces the molten glass within The neck-mold lowers by gravity` IOO IIO

the press-mold and into the neck-mold as required to form the blank required for the subsequent blowing operation. During the lowering of the plunger into the press-mold the mold-ringj enters the neck-mold and a complete blank is formed, as shown in Fig.

Y III, and suspended from or attached to the neck-mold. Vvlhen the blank has been formed within the press-mold, neck-mold, and moldring, as hereinbefore described, the moldring, plunger, and the neck-mold are elevated the distance required to remove them from the press-mold and to free the blank (that is now suspended from the neck-mold) from the press-mold, as shown in Fig. IV, and accommodate the removal of the press-mold and to permit the passage in under the suspended blank of the blow-mold. Vhen the moldbearing slide CZ has been actuated in the direction and to the extent required to bring the blow-mold in under and into registry with the suspended blank, the blow-plate is simultaneously actuated into an operative position upon t-he neck-mold, and thereupon the plunger is again lowered, so as to permit the lowering of the neck-mold by gravity upon the blow-mold, and of course during the lowering` of the neck-mold the blow-plate descends by gravity with the neck mold. When the neck-mold and the blow-platehave been thus lowered, the plunger is by the Voperation of the cams r depressed and caused to bear downwardly upon the blow-plate and retains the latter in its operative position upon the neck-mold. The valve that controls the supply of wind or air under pressure to the blow-plate is operated simultaneously with the operation of the aforesaid cams, and

' the air under pressure passes to the blowhas been expanded as required, the plunger.

plate and thence enters the chamber of the blank and expands the latter, as indicated in dotted lines, Fig. VI. When the blank is released from the operation of the cams, so as to close the aforesaid valve, whereupon the neck-mold and the blow-mold are opened to accommodate the removal of the iinished article.

Obviously two operators are required to operate the apparatus and are stationed at opposite sides, respectively, of, the machine, and the said operators can take care of several machines arranged in a row. One of the operators attends to the operation of the lever p and to the actuation of the moldbearing slide d in the direction required to bring the laden press-mold in under the neckmold, and the other operator attends to the operation of the blow-mold, blow-plate, and cams r and to the opening and closing of the neck-mold and blow-mold.

The neck-mold (see Figs. VIII, 1X, and X) is divided centrally, as at 70, into two halves or sections that nicely t each other when assembled and rest upon different horizontallyarranged plates or slides 7l and 7l, that are capable ot' slidin g from and toward each other,

and engages slideways 72, formed upon a horizontally-arranged plate 73, that is interposed between fthe slides t and a horizontally-arranged plate 74, that partially surrounds the neck-mold. The plate 74 and plate 73 are secured to the slides t t by screws 75, and the plate 73 is cut away centrally to accommodate the location of the neck-mold. The two neckmold sections rest upon and are secured to the different slides 7l and 7l, respectively. Each slide 7l has upon its under side a depending lug or pin 76, that engages a camforming slot or elongated hole 77, formed in a horizontally-arran ged cam-plate 78, capable of being turned in a horizontal plane. Plate 7S rests upon and is seated and conned within a recess 80, formed in the plate 7-1. The said plate 7S is provided with a handle 79 for turning the same. The plate 78 is provided, therefore, with two slots or holes 77 and 77, arranged a suitable distance apart, and one ot' the said slots or holes is engaged by the depending pin or lug of one of the slides 7l, and the other slot or hole 77is engaged by the other depending lug or pin of the other slide. The arrangement, trend, and length of the slots or holes 77 are such that the neck-mold sections are closed together or separated lthe distance required to permit the removal of the vnished glass article therefrom, according as the aforesaid cam-plate is turned or oscillated in the one or the other direction. The plate 73 is slotted, as at 8l, to accommodate the lo-` cation and operation of the pins 76. The slides t t and the plates 73 and 74 constitute a vertically-movable carriage that carries the neck-mold and is provided with the slideways for the slides that bear the neck-mold sections and carries the mechanism employed for moving the said mold-sections apart or close them together, according as the neck-mold is to be opened or closed.

The blow-mold is composed of three sections--viz., two upright sections 85 and 85, forming opposite sides, respectively, of the mold, and a horizontally-arranged section 86, forming the bottom ofthe mold. (See Figs. XI and XII.) The said mold-sections are suitably constructed to render them capable of nicely fitting one another when assembled. The blowmold rests upon and is removably secured to a base 87,that is divided centrally of the mold,as` at S8, into two parts or arms 89 and 89, that atl the joint formed between the side sections of the mold are pivoted together vertically, as at 90, and to the mold-bearing slide d, so as to render the said parts 89 and 89 capable of being swung apart or toward each other. Each slide-A section of the blow-mold has upon its under` side (see Figs.XIl and XIII) any suitable number of depending lugs or pins 91. The pins or lugs 91 of one of the mold-sections 85 engagescorresponding holes 02, formed in one of the base-sections SS, and the lugs or pins 91 of the other mold-section 85 engage corresponding holes formed in the other base-section. Hence each mold-section is prevented ICO IIO

' derneath the said mold-section.

from displacement upon the base-'section un- Each basesection is provided upon its under lside with a depending lug or pin 93, that engages a slot or elongated hole l94:, formed in a horizontally-arranged cam-plate 95, that is capable'of being oscillated within a recess 96, formed in the slide d, which recess has its surrounding wall arranged as required to prevent displacement of the plate upon the said slide. The plate has a handle 97 for operating the same. By the construction hereinbefore described it will be observed that the cam-plate has two slots or holes 94 and 94 arranged a suitable distance apart, that one 0f the said slots or holes is engaged by the pin or lng 93 of one of the base-sections, and that the other slot or hole 94 is engaged by the depending lug or pin 93 of the other base-section. The arrangement, trend, and length of the slots or holes 9J; are such that the side sections of the mold are closed'together or separated, as required, to permit the movement of the finished glass article from the mold, according as the camplate 95 is oscillated in the one or the other direction. The bottom of the mold is provided upon its under side and centrally with a depending stem 98, that extends into and snugly engages a corresponding hole 99, formed in the cam-plate 95, and the sections of the base are suitably cut away at their adjacent edges to accommodate the location of the said stem. The bottom of the mold is therefore removable and can readily be replaced by another bottom having a different design.
